true end of the subject, break the bumpalong loop, to force a match
failure, except when doing partial matching, when we let the next cycle
run at the end of the subject. To see why, consider the pattern
/(?<=abc)def/, which partially matches "abc", even though the string
does not contain the starting character "d". If we have not reached the
true end of the subject (PCRE2_FIRSTLINE caused end_subject to be
temporarily modified) we also let the cycle run, because the matching
string is legitimately allowed to start with the first code unit of a
newline. */
